       6. The image forming device of  claim 1 , further comprising:
 a system data storage unit to store system data; 
 wherein the control unit performs the at least one diagnosis by checking the system data stored in the system data storage unit if the at least one diagnostic item corresponding to the at least one input keyword relates to a characteristic of the image forming device. 
 
     
     
       7. The image forming device of  claim 1 , further comprising:
 an output unit to output a message to report a result of the at least one diagnosis; and 
 an engine part to perform an image forming operation and to output a printed document; 
 wherein the control unit outputs the result of the at least one diagnosis through at least one of the output unit and the engine part in the form of a message or a printed document if the at least one diagnosis corresponding to the at least one diagnostic item is completed. 
 
     
     
       8. The image forming device of  claim 1 , wherein the control unit searches for all diagnostic items having the same keyword as the at least one input keyword among the diagnostic items stored in the storage unit if the keyword is inputted and performs a diagnosis for each diagnostic item associated with the at least one input keyword. 
     
     
       9. The image forming device of  claim 1 , wherein the keyword information stored in the storage unit is editable metadata for at least one respective diagnostic item. 
     
     
       10. A system diagnosis method for an image forming device, comprising:
 receiving an input of at least one keyword; 
 matching information corresponding to at least one diagnostic item for which at least one keyword is to be set with keyword set information corresponding to the at least one keyword to be set and storing the keyword set information corresponding to the at least one diagnostic item matched; 
 searching pre-stored information for at least one diagnostic item that corresponds to the at least one input keyword; and 
 performing at least one diagnosis of the image forming device according to the searched pre-stored information for the at least one corresponding diagnostic item. 
 
     
     
       11. The system diagnosis method of  claim 10 , wherein the performing of the at least one diagnosis includes performing a self-test of an engine part of the image forming device to perform an image forming operation if the at least one searched diagnostic item relates to the image forming operation and checking a result of the self-test. 
     
     
       12. The system diagnosis method of  claim 10 , wherein the performing of the at least one diagnosis includes confirming pre-stored system data if the at least one searched diagnostic item relates to a characteristic of the image forming device. 
     
     
       13. The system diagnosis method of  claim 10 , further comprising:
 outputting a result of the at least one diagnosis in the form of a printed document or a message if the at least one diagnosis is completed. 
 
     
     
       14. The system diagnosis method of  claim 10 , further comprising:
